Shahnaz Husain A bedtime beauty care routine is of much importance, so that the skin is cleansed of make-up, pollutants, dirt and all the impurities that are deposited on it during the day. Also, all the repair and restoration of the body take place when we sleep. The cell renewal process also carries on at night when the body is at rest. Therefore, we should ensure that the skin is clean and the pores are free, so that the skin's repair and renewal can be carried out properly. If the skin is normal to dry, it should also be nourished at night, especially during the dry season. As already mentioned, night time cleansing is of utmost importance. Whatever the type or tex- ture of the skin, it requires thorough cleansing at night. Before it is cleansed, the skin surface is covered with a film of dirt, stale sweat and oil deposits, stale make-up and pollutants. These not only upset the normal balance of the skin, but also hamper its natural functions. Night time pampering of the skin helps us to give special care to particular areas, like the area around the eyes, the neck and hands. These are areas which are the earliest to show signs of age. A nightly rou- tine helps to delay the formation of lines and wrinkles, keeping the skin smooth and youthful. It also keeps the skin and facial muscles toned, strengthening the supportive tissues and pre- serving the elasticity and resilience of the skin. Proper and regular care, according to its needs, keeps the skin healthy and free from problems. During the day, the skin basically needs pro- tection from UV rays of the sun and air pollutants that cause damage to the skin and also deplete moisture. This can be done by using sunscreens, day creams, moisturizers and protective creams, depending on the skin type and condition. Day time care also involves cleansing and toning, but protection is the main aspect. Night time care basically involves restoration and maintenance of the skin, as well as preparing it for the night. It involves thorough cleansing, including the removal of make-up, care of the area around eyes, nourishing and massage of the skin. If the skin is oily, or if there is acne, night care may also involve the application of products to control the condition. HERE ARE SOME DO'S AND DON'TS OF NIGHT CARE: Do's Products for cleansing should be select- ed according to skin type and individual needs. For example, if the skin is dry, a rehy- drant cleansing gel should be used. For oily and combination skin, a cleansing lotion or light cleansing milk may be used. For acne, pimples or rashy skin, it is better to use a medicated cleanser. After cleansing, the skin should be wiped with a rose based skin tonic, using cotton wool. If the skin is dry, nourish and massage it with a nourishing cream. Apply it on the face and massage it with outward and slightly upward movements. Wipe off excess cream with moist cotton wool before bedtime. Apply the cream on the neck too and massage it with both hands, starting from the chin and going downwards. The pressure should not be applied when bring- ing the hands back to the chin, but only as you massage downwards. This helps to delay formation of lines on the neck and also reduces double chins. For all skin types, an under-eye cream should be applied around the eyes and wiped off with moist cotton wool after 15 minutes. The hands may be massaged with a hand cream, especially around the nails, so that the cuticle remains soft. If there is acne / pimples, apply medicat- ed lotion on the eruptions and leave on overnight. If there are pimple marks, apply an anti-blemish cream only on the marks and leave on overnight. Don'ts Avoid using oily cleansers and nourish- ing / night creams if the skin is oily. Do not leave cream on around eyes at night, while you sleep. It can lead to puffi- ness around eyes. Wipe off excess cream with moist cotton wool before bedtime. This leaves the pores free, so that repair work can continue effi- ciently. If the skin is very dry, a light mois- turizing lotion may be applied. Bedtime beauty care Dhanak Gupta The concept of ‘Regeneration and Rejuvenation’ is not new. It has existed for as long as the human kind can trace back their existence. By far immortality has been our biggest and unachievable fascination for ages. There are many stories that exemplify the extent to which people have gone to, to gain immortality. For example, elixir (amrit), a mythical potion believed to cure all ills, when drunk, grants eternal life and youth. Elixir has been widely described in Hindu, Buddhist and Chinese scrip- tures but in the modern day there is no evidence of its existence. Regeneration means the process of regrowth and repair of the disease parts of the body. Scientifically, it relates to everyday wear and tear and mainte- nance of normal working of our body organs and systems. Human bodies are very complex and there are more than one repair systems in action that ensure our bodies can withstand everyday dam- age and repair them without making us consciously realise it. This is where the Stem Cells come into play. Adult Stem Cells are one of the repair systems in action in our bodies. A stem cell is a cell that has not yet differentiat- ed, i.e, it is not yet a mature cell with a function but these cells have the poten- tial to grow and become a differentiated or a mature cell that can perform one specific function. Stem cells are present in all organs. For example, a stem cell in skin has the potential to form the skin cells that produces melanin and a pan- creatic stem cell can form the pancreat- ic cell that can form insulin under the right circumstances. Not only that, every organ has one or more different stem cell types present. This means you can have more than one back up systems of stem cells in the same organ. For instance, skin has atleast three, brain has atleast two and bone marrow has atleast three different stem cell types in them, all involved in the regeneration process. These stem cells are normally in a dormant state, present deep inside the organ, hidden from possible sources of damage such as sunlight. Thus, they need specific triggers to awaken them from dormancy. That trigger can be in the form of a cut or a wound, which stim- ulates the stem cell and causes it to divide and give rise to new cells, which finally repair and replace the damaged organ. This is how the usual repair sys- tem works in our body. An interesting thing to note is that where some organs repair easily like the skin, bone and liv- er, others seem to heal very slowly, like the brain and the heart. It is not because the brain and the heart do not have stem cells but because the stem cells in these organs have lower ability or potency to give rise to new cells. Thus, in other words, though every organ has stem cells, they all have different regenerative abilities and only give rise to organs they are present in. There is another most commonly talked about source of stem cells called the embryonic stem cells. These stem cells are highly lucrative source of regen- eration as they have the capacity to form all types of entire new organs that can be transplanted and used to replace the old worn out organs in our body, bringing us one step closer to immortality and ditch- ing aging. Human embryos are grown in laboratories and stem cells are taken from these embryos to put them inside the patients. Some may say that the embryonic human stem cells are sourced from unborn persons that are sacrificed for other patients cure. Hence, there is a lot of controversy that surrounds embry- onic stem cells and often the morality of using human embryos for scientific research and therapy is under scrutiny, not to mention, the safety issues and side effects that these embryonic stem cells might have and are not fully understood even by the scientific community. This means, more and more scientific research is being done on the stem cells from the adult human bodies and not human embryos. Some of the most common sources of adult stem cells are bone marrow, skin, liver, intestine, teeth, eyes, etc. One of the major problems in harnessing these stem cells are that they are found in very few numbers in our bodies. For example, only one in 10,000 or 15,000 cells in the bone marrow is a stem cell. Stem cells could also be sourced from a donor (another person) but that would lead to immune rejection by the body of the patient. Second problem is that a stem cell from skin may not be useful for repair in the brain, even though getting a stem cell from skin is easier than get- ting a stem cell from deep inside the brain. Thanks to the recent advances in the stem cell biology in the last ten years, sci- entists have managed to generate anoth- er source of stem cells. These are called the human induced pluripotent stem cells (iPSC). These stem cells are creat- ed in a laboratory when a mature body cell is taken and its DNA is changed in a way that it starts behaving like a stem cell. For example, a liver cell is taken from patient’s body, its DNA is repro- grammed and then under the right con- ditions, it converts into a stem cell which can give rise to all the organs of the body like a the pancreas that can be trans- planted back inside the patient. These stem cells behave similar to embryonic stem cells and have the capacity to form different organs with only difference that they are sourced from adult humans and not human embryos. Currently, iPSC is one of the most advanced fields of research in human biology. Finally, the beauty of stem cell ther- apy lies in the idea that, the stem cells taken from a patient’s body may be con- trolled to form entire new organs based on that patient’s customised needs; making the patient his/her own organ donor. As a Scientist, I believe it is the holy grail of immortality. (The author is a final year PhD Student in Division of Cancer and Stem cells, University of Nottingham, UK.) SUNDAY, FEBRUARY 21, 2016 (PAGE-4) BEAUTY TIPS SCIENCE & TECHNOLOGY HEALTHLINES Ram Madhvani's NEERJA is a heroic story of a brave young girl Neerja Bhanot who displayed extraordinary courage during extremely dangerous circumstances. It is a rare film that will make you cry profusely but at the same time scaffold you with strength to raise your voice against injustice and why one must never compromise on self- respect. As a movie watching experience, NEERJA is flaw- less. There's not a single false note. No compromise at the level of storytelling. Bravo! Neerja Bhanot (Sonam Kapoor) is the purser at Panam Airlines. She is a diehard Rajesh Khanna fan and believes that one must live a Big life rather than living for long. She's also a successful model. Her doting mother Rama Bhanot (Shabana Azmi) and an ever encouraging father Harish Bhanot (Yogendra Tiku) love to pamper their Laado. Neerja has a loving suitor in Jaideep (Shekhar Ravjiani). Life seems to be hunky dory. In the present. The ill-fated flight to New York on which Neerja is the head purser gets hijacked in Karachi by the Libya backed Palestinian terrorist group Abu Nidal. The past suddenly percolates in the memory space, for Neerja had earlier been in an abusive marriage and now she was facing abuse from menacing terrorists. Her extraordi- nary courage and presence of mind saved the lives of most of the passengers as she put others before herself. Saiwyn Quadras' smart and gripping screenplay is the backbone of NEERJA. The narrative goes back and forth in a very interesting manner. Ram Madhvani brings amazing perspective to the real life story by giving various points of view. When Neerja tells the head of the terrorist group that she's just doing her duty the way they are doing theirs, it drives home a point. The terrorists are shown to be edgy and nervous. They are as afraid as the harried passengers. The opportune manner in which Neerja drives strength from the flashbacks of her family life (good and bad) literally pushes the right buttons of emotions among the audience. Sanyukta Chawla Shaikh's dialogues are bang- on in communicating the angst, pathos and fear very well. Sonam Kapoor has delivered the performance of a lifetime. The fact that Sonam has displayed astound- ing courage in real life at many an occasion by speaking about con- tentious subjects of national impor- tance without bothering about the hate coming her way, she carries a certain credibility in this context that is very believable. What's laudable is her precision. She never overdoes. Most importantly she internalizes the courageous spirit of Neerja who had a sound head during inhuman circumstances. When Sonam cries, you'd cry with her. Also, by the end you'd feel like saluting the heroic spirit of both Neerja as well as Son- am. Shabana Azmi adds another feather to her illustrious cap. The entertaining way in which she speaks Punjabi, the state of temporarily losing one's mind and the way she becomes Rama Bhanot is a good enough reason in itself to watch the film. Yogendra Tiku as Harish Bhanot is very effective in instilling fearlessness in his daughter. One of the terrorists by the name of Khalil looks every bit a hard core terrorist with a maniacal bent of mind. Excellent casting. Mitesh Mirchandani's cinematography is excellent. At times it is hand held, making it that much more real. Mon- isha R Baldawa's editing is spot on. The songs are not allowed to be played for full duration, everything is kept that's essen- tial and there's nothing superfluous in the film. Vishal Khu- rana's music and background score adds value to the film. 'Jeete Hain Chal' and 'Gehra Ishq' are wonderful composi- tions and brilliantly written by wordsmith Prasoon Joshi. Vishal's background score adds the necessary fear and sus- pense. On the whole, NEERJA is a must watch ode to the youngest recipient of the highest civilian honour Ashok Chakra for displaying extraordinary courage and human kindness. It is a film that will make you stand up for what's genuinely Right without bothering about nationality, reli- gion, sex, cast or colour of the skin. Most importantly as a movie watching experience, you'll be glued to the movie screen with tears and admiration welling up in your eyes. NEERJA is a movie that will make you a better person. Don't miss it!

It is actually a group of different cancers of the blood cells ,can be acute or chronic, and people with chronic leukemias may not notice any symptoms before the condition is diagnosed with a blood test. There are four main types of leukemias 1.Acute Myeloid Leukemia (AML) 2.Acute Lymphoblastic Leukemia(ALL) 3.Chronic Myeloid Leukemia(CML) 4.Chronic Lymphocytic Leukemia(CLL) The number of new cases of leukemia was 13.3 per 100,000 men and women per year.In 2012, leukemia developed in 352,000 people globally and caused 265,000 deaths, represents about 3% of the almost seven million deaths due to cancer that year,. It is the most common type of cancer in children, with almost 75% of leukemia cases in children being the acute lymphoblastic type. However, about 90% of all leukemias are diagnosed in adults, with AML and CLL ,being most common in adults. In India, the average rate of Leukemia incidence is lower than that of devel- oped countries, ALL is commonest Leukemia in Chil- dren & CML amongst Adults. But,in the past five years, there has been a 30 % rise in the number of victims affected by Leukemia in India ,especially in Childhood Leukemia where mortality is high. Leukemia begins in the immature cells of the bone marrow in the central cavities of bones. The bone marrow produces all types of blood cells: red blood cells that carry oxygen and other materials to the tissues of the body, white blood cells that fight infection, and platelets that help the blood clot. Hundreds of billions of new blood cells are produced in the bone marrow each day, pro- viding the body with a constant supply of fresh, healthy cells. In a patient with leukemia, many of the white blood cells produced in the bone marrow do not mature normally. These abnormal cells, called leukemic cells, are unable to fight infection the way healthy white cells can. As they accumulate, the leukemic cells also interfere with the production of other blood cells. Eventually, the body has too few red cells for supplying oxygen to the body’s tissues, too few platelets for proper clotting and too few healthy white cells for fighting infection. As a result, people with leukemia are at risk for bruising, bleeding and infections. Dr. Rajeev who himself, is a Hematologist, has treated and cured many leukemia patients in his practice says In order to fight leukemia it is important to understand the types of leukemia and how it can be prevented or detected early so that it can treated as early as possible. TYPES OF LEUKEMIA 1. Acute Myeloid Leukemia (AML) : Acute myeloid leukemia is the most common type of leukemia in adults, although it also can occur in chil- dren. If untreated, this form of leukemia usually progresses quickly. 2. Chronic Myeloid Leukemia (CML) : Chronic myeloid leukemia originates from the presence of a genetic abnormality in blood cells, called the Philadelphia chromosome, and progresses through distinct phases. CML occurs main- ly in adults, but a very small number of chil- dren also develop this disease. 3. Acute Lymphoblastic Leukemia (ALL) : Acute lymphoblastic leukemia is the most common type of leukemia in young children in developed countries, but it also affects adults, especially those ages 65 and older. 4. Chronic Lymphocytic Leukemia (CLL): Chronic lymphocytic leukemia usu- ally gets worse slowly. CLL is the second most common form of leukemia in adults and rarely occurs in children. More than half of people diagnosed with CLL are older than 70, and cases rarely occur in individuals younger than 40. For the diagnosis of leukemia, the doctor must examine cells from the blood and, in most cases, the bone marrow. An ini- tial blood test (complete blood count [CBC]) showing an abnormal white cell count may indicate the need for a bone marrow biopsy to confirm the diagnosis and to identify the specific type of leukemia. During this procedure, the doctor removes a sample of bone marrow tissue (biopsy) from a pelvic bone and tests the sample for can- cer cells. Treatment options of Leukemia depends on the type of leukemia * Chemotherapy is the administration of drugs that kill rapidly dividing cells such as leukemia or other cancer cells. * Biological therapy or immunotherapy uses the body’s immune system to fight cancer, using antibodies to target and destroy leukemia cells, example of a monoclonal antibody is Alemtuzumab used in the treatment of CLL & Inter- ferons in the treatment of CML. * Targeted therapy ,are drugs that interfere with one specific property or func- tion of a cancer cell, rather than acting to kill all rapidly grow- ing cells indiscriminately like chemotherapy . Imatinib and dasatinib are examples of targeted therapies that are used to treat CML * Sometimes,Radiation therapy is used for leukemia in the central nervous system or testicles as well as for pain caused by bone destruc- tion. However, radiation is not the primary treatment for leukemia. * Stem cell transplant, high doses of chemotherapy and/or radiation are given to destroy leukemia cells along with normal bone marrow. Then, trans- plant stem cells are delivered by an intravenous infusion. The stem cells trav- el to the bone marrow and begin producing new blood cells. Stem cells may come from the patient , known as autologous stem cell transplantation or from a donor, known as allogeneic stem cells transplant , Stem Cell or Bone Marrow Transplants are probably the best bet for a cure in many cases of leukemia Esp AML & ALL. It is performed when leukemia is in remission or when the patient relapses during or after treatment. Now a days, patients are surviving longer, thanks mainly to advances in treatment and medical facilities. Acute Lymphoblastic Leukemia (ALL), for example, represents one of the most dramatic success stories in cancer treat- ment. Almost 90 percent of children diagnosed with the disease attain remis- sion. Also Adult patients treated for ALL have an 80 percent to 90 percent chance of attaining remission. Patients treated for Acute Myeloid Leukemia (AML) have a 60 percent to 70 percent chance of remission; about 20 percent of those survive at least three years, with a possibility of a full cure.

A bedtime beauty care routine is ofmuch importance, so that the skin iscleansed of make-up, pollutants, dirtand all the impurities that are depositedon it during the day. Also, all the repairand restoration of the body take placewhen we sleep. The cell renewalprocess also carries on at night whenthe body is at rest. Therefore, we shouldensure that the skin is clean and thepores are free, so that the skin's repairand renewal can be carried out properly.If the skin is normal to dry, it shouldalso be nourished at night, especiallyduring the dry season.

As already mentioned, night time cleansing isof utmost importance. Whatever the type or tex-ture of the skin, it requires thorough cleansing atnight. Before it is cleansed, the skin surface iscovered with a film of dirt, stale sweat and oildeposits, stale make-up and pollutants. Thesenot only upset the normal balance of the skin, butalso hamper its natural functions. Night timepampering of the skin helps us to give special careto particular areas, like the area around the eyes,the neck and hands. These are areas which arethe earliest to show signs of age. A nightly rou-

tine helps to delay the formation of lines andwrinkles, keeping the skin smooth and youthful.It also keeps the skin and facial muscles toned,strengthening the supportive tissues and pre-serving the elasticity and resilience of the skin.Proper and regular care, according to its needs,keeps the skin healthy and free from problems.

During the day, the skin basically needs pro-tection from UV rays of the sun and air pollutantsthat cause damage to the skin and also depletemoisture. This can be done by using sunscreens,day creams, moisturizers and protective creams,depending on the skin type and condition. Day

time care also involves cleansing and toning, butprotection is the main aspect. Night time carebasically involves restoration and maintenanceof the skin, as well as preparing it for the night.It involves thorough cleansing, including theremoval of make-up, care of the area aroundeyes, nourishing and massage of the skin. If theskin is oily, or if there is acne, night care may alsoinvolve the application of products to control thecondition.

Do'sProducts for cleansing should be select-

ed according to skin type and individualneeds. For example, if the skin is dry, a rehy-drant cleansing gel should be used. For oilyand combination skin, a cleansing lotion orlight cleansing milk may be used. For acne,pimples or rashy skin, it is better to use amedicated cleanser.

If the skin is dry, nourish and massage itwith a nourishing cream. Apply it on theface and massage it with outward andslightly upward movements. Wipe offexcess cream with moist cotton wool beforebedtime. Apply the cream on the neck tooand massage it with both hands, startingfrom the chin and going downwards. Thepressure should not be applied when bring-ing the hands back to the chin, but only asyou massage downwards. This helps todelay formation of lines on the neck and alsoreduces double chins.

For all skin types, an under-eye creamshould be applied around the eyes andwiped off with moist cotton wool after 15minutes.

The hands may be massaged with a handcream, especially around the nails, so thatthe cuticle remains soft.

If there is acne / pimples, apply medicat-ed lotion on the eruptions and leave onovernight. If there are pimple marks, applyan anti-blemish cream only on the marksand leave on overnight.

Don'tsAvoid using oily cleansers and nourish-

ing / night creams if the skin is oily.Do not leave cream on around eyes at

night, while you sleep. It can lead to puffi-ness around eyes.

Wipe off excess cream with moist cottonwool before bedtime. This leaves the poresfree, so that repair work can continue effi-ciently. If the skin is very dry, a light mois-turizing lotion may be applied.

The concept of ‘Regeneration andRejuvenation’ is not new. It has existedfor as long as the human kind can traceback their existence. By far immortalityhas been our biggest and unachievablefascination for ages. There are manystories that exemplify the extent towhich people have gone to, to gainimmortality. For example, elixir (amrit),a mythical potion believed to cure allills, when drunk, grants eternal life andyouth.

Human bodies arevery complex and there are more thanone repair systems in action that ensureour bodies can withstand everyday dam-age and repair them without making usconsciously realise it.

Adult Stem Cells are one of the repairsystems in action in our bodies. A stemcell is a cell that has not yet differentiat-ed, i.e, it is not yet a mature cell with afunction but these cells have the poten-tial to grow and become a differentiatedor a mature cell that can perform onespecific function. Stem cells are presentin all organs. For example, a stem cell inskin has the potential to form the skincells that produces melanin and a pan-creatic stem cell can form the pancreat-ic cell that can form insulin under theright circumstances. Not only that, everyorgan has one or more different stem celltypes present. This means you can havemore than one back up systems of stemcells in the same organ. For instance,skin has atleast three, brain has atleasttwo and bone marrow has atleast threedifferent stem cell types in them, allinvolved in the regeneration process.

These stem cells are normally in adormant state, present deep inside theorgan, hidden from possible sources ofdamage such as sunlight. Thus, theyneed specific triggers to awaken themfrom dormancy.

Ram Madhvani's NEERJA is a heroic story of a braveyoung girl Neerja Bhanot who displayed extraordinarycourage during extremely dangerous circumstances. It is arare film that will make you cry profusely but at the sametime scaffold you with strength to raise your voice againstinjustice and why one must never compromise on self-respect. As a movie watching experience, NEERJA is flaw-less. There's not a single false note. No compromise at thelevel of storytelling. Bravo!

Neerja Bhanot (Sonam Kapoor) is the purser at PanamAirlines. She is a diehard Rajesh Khanna fan and believesthat one must live a Big life rather than living for long. She'salso a successful model. Her doting mother Rama Bhanot(Shabana Azmi) and an ever encouraging father HarishBhanot (Yogendra Tiku) love to pamper their Laado. Neerjahas a loving suitor in Jaideep (Shekhar Ravjiani). Life seemsto be hunky dory. In the present. The ill-fated flight to NewYork on which Neerja is the head purser gets hijacked inKarachi by the Libya backed Palestinian terrorist group AbuNidal. The past suddenly percolates in the memory space, forNeerja had earlier been in an abusive marriage and now shewas facing abuse from menacing terrorists. Her extraordi-nary courage and presence of mind saved the lives of most ofthe passengers as she put others before herself.

Theentertaining way in which she speaks

Punjabi, the state of temporarily losingone's mind and the way she becomes Rama Bhanot is a goodenough reason in itself to watch the film. Yogendra Tiku asHarish Bhanot is very effective in instilling fearlessness inhis daughter. One of the terrorists by the name of Khalil looksevery bit a hard core terrorist with a maniacal bent of mind.Excellent casting.

Mitesh Mirchandani's cinematography is excellent. Attimes it is hand held, making it that much more real. Mon-isha R Baldawa's editing is spot on. The songs are not allowedto be played for full duration, everything is kept that's essen-tial and there's nothing superfluous in the film. Vishal Khu-rana's music and background score adds value to the film.'Jeete Hain Chal' and 'Gehra Ishq' are wonderful composi-tions and brilliantly written by wordsmith Prasoon Joshi.Vishal's background score adds the necessary fear and sus-pense.

On the whole, NEERJA is a must watch ode to theyoungest recipient of the highest civilian honour AshokChakra for displaying extraordinary courage and humankindness. It is a film that will make you stand up for what'sgenuinely Right without bothering about nationality, reli-gion, sex, cast or colour of the skin. Most importantly as amovie watching experience, you'll be glued to the moviescreen with tears and admiration welling up in your eyes.NEERJA is a movie that will make you a better person. Don'tmiss it!

MOVIE-REVIEW

The word leukemia, which means ‘white blood’, is derived from the twoGreek words leukos, meaning “white”, and haima , meaning “blood”, is a groupof cancers that usually begin in the bone marrow and result in high numbersof abnormal white blood cells , was named by pathologist Rudolf Virchow in1845. It is actually a group of different cancers of the blood cells ,can be acuteor chronic, and people with chronic leukemias may not notice any symptomsbefore the condition is diagnosed with a blood test.

There are four main types of leukemias1.Acute Myeloid Leukemia (AML) 2.Acute Lymphoblastic Leukemia(ALL)3.Chronic Myeloid Leukemia(CML)4.Chronic Lymphocytic Leukemia(CLL)

The number of new cases of leukemia was 13.3 per 100,000 men and womenper year.In 2012, leukemia developed in 352,000 people globally and caused265,000 deaths, represents about 3% of the almost seven million deaths dueto cancer that year,. It is the most common type of cancer in children, withalmost 75% of leukemia cases in children being the acute lymphoblastic type.However, about 90% of all leukemias are diagnosed in adults, with AML andCLL ,being most common in adults.

In India, the average rate of Leukemia incidence is lower than that of devel-oped countries, ALL is commonest Leukemia in Chil-dren & CML amongst Adults. But,in the past five years,there has been a 30 % rise in the number of victimsaffected by Leukemia in India ,especially in ChildhoodLeukemia where mortality is high.

Leukemia begins in the immature cells of the bone marrow in the centralcavities of bones. The bone marrow produces all types of blood cells: red bloodcells that carry oxygen and other materials to the tissues of the body, whiteblood cells that fight infection, and platelets that help the blood clot. Hundredsof billions of new blood cells are produced in the bone marrow each day, pro-viding the body with a constant supply of fresh, healthy cells. In a patient withleukemia, many of the white blood cells produced in the bone marrow do notmature normally. These abnormal cells, called leukemic cells, are unable tofight infection the way healthy white cells can. As they accumulate, the leukemiccells also interfere with the production of other blood cells. Eventually, the bodyhas too few red cells for supplying oxygen to the body’s tissues, too few plateletsfor proper clotting and too few healthy white cells for fighting infection. As aresult, people with leukemia are at risk for bruising, bleeding and infections.

Dr. Rajeev who himself, is a Hematologist, has treated and cured manyleukemia patients in his practice says In order to fight leukemia it is importantto understand the types of leukemia and how it can be prevented or detectedearly so that it can treated as early as possible.

TYPES OF LEUKEMIA 1. Acute Myeloid Leukemia (AML) : Acute myeloid leukemia is the

most common type of leukemia in adults, although it also can occur in chil-dren. If untreated, this form of leukemia usually progresses quickly.

2. Chronic Myeloid Leukemia (CML) : Chronic myeloid leukemia

originates from the presence of a geneticabnormality in blood cells, called thePhiladelphia chromosome, and progressesthrough distinct phases. CML occurs main-ly in adults, but a very small number of chil-dren also develop this disease.

3. Acute Lymphoblastic Leukemia(ALL) : Acute lymphoblastic leukemia is themost common type of leukemia in youngchildren in developed countries, but it alsoaffects adults, especially those ages 65 andolder.

4. Chronic Lymphocytic Leukemia(CLL): Chronic lymphocytic leukemia usu-ally gets worse slowly. CLL is the secondmost common form of leukemia in adultsand rarely occurs in children. More than halfof people diagnosed with CLL are older than70, and cases rarely occur in individualsyounger than 40.

For the diagnosis of leukemia, thedoctor must examine cells from the bloodand, in most cases, the bone marrow. An ini-tial blood test (complete blood count [CBC])showing an abnormal white cell count mayindicate the need for a bone marrow biopsyto confirm the diagnosis and to identify thespecific type of leukemia. During this procedure, the doctor removes a sampleof bone marrow tissue (biopsy) from a pelvic bone and tests the sample for can-cer cells.

Treatment options of Leukemia depends on the type of leukemia* Chemotherapy is the administration of drugs that kill rapidly dividing

cells such as leukemia or other cancer cells. * Biological therapy or immunotherapy uses the body’s immune system to

fight cancer, using antibodies to target and destroy leukemia cells, example ofa monoclonal antibody is Alemtuzumab used in the treatment of CLL & Inter-ferons in the treatment of CML.

* Targeted therapy ,are drugs that interfere with one specific property or func-tion of a cancer cell, rather than acting to kill all rapidly grow-ing cells indiscriminately like chemotherapy . Imatinib anddasatinib are examples of targeted therapies that are used totreat CML

* Sometimes,Radiation therapy is used for leukemia inthe central nervous system or testicles as well as for pain caused by bone destruc-tion. However, radiation is not the primary treatment for leukemia.

* Stem cell transplant, high doses of chemotherapy and/or radiation aregiven to destroy leukemia cells along with normal bone marrow. Then, trans-plant stem cells are delivered by an intravenous infusion. The stem cells trav-el to the bone marrow and begin producing new blood cells. Stem cells maycome from the patient , known as autologous stem cell transplantation or froma donor, known as allogeneic stem cells transplant ,

Stem Cell or Bone Marrow Transplants are probably the best bet for a curein many cases of leukemia Esp AML & ALL. It is performed when leukemia isin remission or when the patient relapses during or after treatment.

Now a days, patients are surviving longer, thanks mainly to advances intreatment and medical facilities. Acute Lymphoblastic Leukemia (ALL), forexample, represents one of the most dramatic success stories in cancer treat-ment. Almost 90 percent of children diagnosed with the disease attain remis-sion. Also Adult patients treated for ALL have an 80 percent to 90 percentchance of attaining remission. Patients treated for Acute Myeloid Leukemia(AML) have a 60 percent to 70 percent chance of remission; about 20 percentof those survive at least three years, with a possibility of a full cure.
